Roll To Roll Slitting And Rewinding Machine

Rewinding Machine operating procedures - Preparation for rewinding.
1. The crane operator and the rewinding personnel first check whether the information on the parent roll tracking slip on the base paper meets the requirements of the technical standards, specifications and specifications.
2. Check whether the labels of various paper diseases on both ends of the base paper roller are clear and consistent with the contents on the tracking sheet.
3. The crane operator should operate carefully according to the safe operation rules of the driving.
4. Place the base paper roll on the unloading frame smoothly, place the drum groove on the shaft head, place the track groove in the locked position, and connect it with the hydraulic coupling.
5. Jog the left and right shift buttons of the exit tray to bring the ends of the web to a position that can be trimmed (to be threaded).
6. The operator should make a detailed record of the paper (such as shift, shift, production date, roll time and paper roll code, etc.).

1. Rewinder structure and working principle

1.1 Structure
The rewinder is generally composed of a unwinding roll (also referred to as a paper take-off roll), a guide roll, a slitting mechanism, a platen roll, a take-up bottom roll (including a front bottom roll and a rear bottom roll), and a double bottom roll. The machine is characterized by two rotating drums to replace and support the take-up reel, usually with or without a rotating platen roller pressed against the top of the reel in the take-up, the take-up reel is taken up The main structure (has become the front and rear bottom rollers respectively). Under normal circumstances, the surface of the front bottom roller is rough, and the surface of the rear bottom roller is relatively smooth. They are connected to the motor through the reduction gear box. The platen roller, also called the load roller, acts to create a downward pressure whose pressure is the difference between its own weight and the load roller lifting pressure. The unwinding roller is composed of a leg paper holder, a unwinding roller coupling, a unwinding roller clamping mechanism, and a unwinding motor. Longitudinal cutters generally have book holders side by side on the same axis, mainly used to cut off the change. Cut a certain width of sheet paper to the required width as needed. Two tension sensors are placed on the tension roller to receive the web tension.

4 Research significance and content
Due to the application and development of frequency conversion technology and computer network technology in the field of industrial control, the establishment of AC drive control system based on field bus has become an effective way to solve the above shortcomings and limitations. Taking PLC as the control unit, the inverter is the execution unit, and the OP operation panel is the operating unit to form the all-digital field bus rewinder AC rotation control system. Based on this assumption, in order to reduce the investment, the original mechanical part and hydraulic part of the system are basically maintained, the original DC rotating system is transformed into an AC rotating system, the solenoid valve and some worn mechanical parts are replaced; and the OP270 man-machine interface is used instead of the machine. Buttons and analog meters, and a part of the mechanical buttons, so that workers can operate on the OP270 or on the console buttons, complement each other, increasing the flexibility of operation.
